There’s a reason that blockchain startups are hot. Technologies come and go over the years and raise their share of hype, but few can match the enthusiasm that has been shown for blockchain technology.

Blockchain is the brainchild of Satoshi Nakamoto, who may or may not be real and may or may not be one person or a group of people. All that is known is that Nakamoto is also the brains behind Bitcoin. Blockchain is in fact the technology behind Bitcoin but the two are totally separate. Blockchain provides the means to record and store Bitcoin transactions, but the blockchain technology has many uses beyond Bitcoin.

Blockchains are distributed ledgers, and they accept input from many different parties. So think of them as something akin to a Wikipedia page, where anyone can edit it. Unlike Wikipedia, where one person can change a page, a blockchain ledger can only be changed by people within the group who have permissions.

With a permissioned blockchain, each participant has a unique identity, and their identity has permissions of what they can and cannot do. Blockchain uses policies to constrain network participation and access to transaction details.

So unlike Wikipedia, there is no need for central control. If someone makes a bad or negative entry to a Wikipedia page, the admins can undo it. That is not the case with blockchain, where the distribution database is done by consensus where every node in the blockchain network comes to the same conclusion about a record. You get the ability to make changes to a Blockchain by ownership of a private key for authentication.

Blockchain Startups

There are many other potential uses, as the many blockchain startups in this list will show. This list, as long as it is, is by no means complete. Yet here are 35 blockchain startups worth watching – and many more are entering the field.

Initial Coin Offerings (ICOs) are means to launch a new cryptocurrency, like BitCoin, except they sell ownership or royalties to a project instead of money.
